The existence of an IEEE standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and

13、 standard is translated, only the English version published by IEEE should be considered the approved IEEE standard. Official statements A statement, written or oral, that is not processed in accordance with the IEEE-SA Standards Board Operations Manual shall not be considered or inferred to be the
14、official position of IEEE or any of its committees and shall not be considered to be, or be relied upon as, a formal position of IEEE. At lectures, symposia, seminars, or educational courses, an individual presenting information on IEEE standards shall make it clear that his or her views should be c

Comments on standards Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of membership affiliation with IEEE. However, IEEE does not provide consulting informatio
16、n or advice pertaining to IEEE Standards documents. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Since IEEE standards represent a consensus of concerned interests, it is important that any responses to comment
17、s and questions also receive the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instant response to comments or questions except in those cases where the matter has previously been address
18、ed. For the same reason, IEEE does not respond to interpretation requests. Any person who would like to participate in revisions to an IEEE standard is welcome to join the relevant IEEE working group.

25、at any time by the issuance of new editions or may be amended from time to time through the issuance of amendments, corrigenda, or errata. An official IEEE document at any point in time consists of the current edition of the document together with any amendments, corrigenda, or errata then in effect
26、. Every IEEE standard is subjected to review at least every ten years. When a document is more than ten years old and has not undergone a revision process, it is reasonable to conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Users are caut

30、d, no position is taken by the IEEE with respect to the existence or validity of any patent rights in connection therewith. If a patent holder or patent applicant has filed a statement of assurance via an Accepted Letter of Assurance, then the statement is listed on the IEEE-SA Website at http:/stan

Letters of Assurance may indicate whether the Submitter is willing or unwilling to grant licenses under patent rights without compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair discrimin

The IEEE is not responsible for identifying Essential Patent Claims for which a license may be required, for conducting inquiries into the legal validity or

Users of this standard are expressly advised that determination of the valid
34、ity of any patent rights, and the risk of infringement of such rights, is entirely their own responsibility. Further information may be obtained from the IEEE Standards Association.

39、on This introduction is not part of IEEE Std 1901.2a-2015, IEEE Standard for Low-Frequency (less than 500 kHz) Narrowband Power Line Communications for Smart Grid ApplicationsAmendment 1. This standard is designed to enable low-frequency (500 kHz) narrowband power line communications (PLC) over indo
40、or and outdoor electrical wiring. The standard supports data rates of up to 500 kb/s and was developed as the result of a collaborative effort undertaken by a large cross section of the PLC industrys technical experts and stakeholders. It also contains a coexistence mechanism that was developed base
41、d on the requirements provided by the industry and with the input from the Smart Grid Interoperability Panel (SGIP) Priority Action Plan 15 (PAP15). This coexistence mechanism may be used by any PLC technology in this band without implementing the rest of the standard and will be maintained through
42、the IEEE-SA. The project was authorized 25 March 2010. The first draft was available in early January 2011. The first letter ballot was started in January 2012 and received final working group approval on 29 May 2013. Sponsor ballot was completed on 7 September 2013. The document was approved by the
43、 IEEE-SA Standards Board on 31 October 2013. The base standard amendment project was authorized 26 March 2015 and approved by the IEEE SA Standards Board on xx Month 2015. The scope of this amendment is as follows: Change to clarify how and when to encrypt header and payload information elements. Ch
44、ange to the interleaver design to eliminate some drawbacks in certain channels. Insert an attribute into a PHY data primitive so sub-band SNR data can be obtained from the PHY. Change to the frame counter size for security to make it consistent with IEEE Std 802.15.4e- 2012. Insert a beacon attribute Change the zero crossing detector text.
